Installation
Location
Location
Plan location of transceiver and microphone bracket before starting the installation.
Select a location that is convenient for operation, yet does not interfere with the driver or passenger.
The transceiver is usually mounted to the underside of the dash with the microphone bracket beside it.
Mounting and
Connection
Note
The transceiver is held in the universal mounting bracket by two thumbscrews which allow for adjustment at a convenient angle.
The bracket includes two selftapping screws and star washers. The mounting must be mechanically strong, conveniently located.
Mounting and Connection
1 Hold the radio with the mounting bracket in the exact desired location. If there is no interference, remove the bracket and use it as a template to mark the location for the mounting screws.
Installation
Note
Before installing the CB radio, visually check the vehicle’s battery connection to determine which terminal, positive or negative, is grounded (positive is the larger of the two) to the engine block (or chassis). A negatively grounded vehicle has its negative lead grounded to the chassis.
3 Connect the antenna cable plug to the receptacle marked “ANT” on the back of the unit.
Note
In positive ground vehicles the red wire goes to the chassis and the black wire is connected to the ignition switch.
2
2 Drill the holes and secure the bracket.

3
Installation
Note
Connecting to an accessory fuse prevents the unit from being left on accidentally, and also permits operating the unit without running the engine.
Note
In positive ground vehicles the red wire goes to the chassis and the black wire is connected to the ignition switch.
4 In a negative grounded vehicle, connect the red lead of the DC power cord to an accessory
12 volt fuse.
5 Connect the black lead to the negative side of the vehicle. This is usually the chassis. Any convenient location with a good electrical contact
(remove paint) may be used.
6 Plug power cable into back of unit marked
“Power”. Be sure to observe polarity markings.
7 Mount the microphone bracket on the right side of the unit (driver’s left) using two screws supplied. Bracket should be placed under the dash so microphone is readily accessible.
8
Attach the 4-pin microphone cable to receptacle on the front of the unit and install unit in bracket securely.

Installation
Antennas Ignition Noise Interference
CB Antenna
Note
For optimum performance in passenger cars the ideal antenna location is on the center of the roof. Second choice is on the center of the trunk.
CB Antenna
Since the maximum allowable power output of the transmitter is limited by the FCC, the antenna is critical in affecting transmission distance. Only a properly matched antenna system will allow maximum power output. Cobra loaded type antenna models are highly recommended for most installations. Consult your Cobra dealer for further details, or call 773.889.3087 and speak to a Cobra representative.
Note
Because many newer trucks feature fiberglass door skins, the outside mirror must be grounded to the chassis..
Note
3-way Combination Antennas are also available which allow operation of all three bands
(AM-FM & CB), using a single antenna. However, this type of antenna usually results in less than normal transmit and receive range when compared to a standard-type “Single
Band” CB antenna. Call
773.889.3087 for further information.
1 A standard antenna connector is provided on the transceiver for easy connection.
Marine Installation
The transceiver will not operate at maximum efficiency in a boat without a ground plate, (unless it has a steel hull). Before attempting installation , consult your dealer for information regarding an adequate grounding system and prevention of electrolysis between fittings in the hull and water.
Use of a mobile receiver at low signal levels is normally limited by the presence of electrical noise. The primary source of noise in automobiles is from the alternator and ignition system.
Typically, when signal level is adequate, the background noise does not present a serious problem.
Also, when extremely low level signals are being received, the transceiver may be operated with the vehicle’s engine turned off. The unit requires very little current and therefore will not significantly discharge the vehicle’s battery.
Even though the Cobra 25 LTD Classic has an automatic noise limiter, in some installations ignition interference may be high enough to make good communications impossible. Many possibilities exist and variations between vehicles require different solutions. Consult your COBRA dealer or a 2-way radio technician for help in locating the source of a severe noise.

The CB Story
A1
The Citizens Band lies between the shortwave broadcast and 10-meter Amateur radio bands, and was established by law in 1949. The Class D two-way communications service was opened in
1959. (CB also includes a Class A citizens band and Class C remote control frequencies.)
FCC Regulations
FCC regulations permit only “transmissions”
(one party to another) rather than “broadcasts”
(to a wide audience). Thus, advertising is not allowed on CB Channels because that is “broadcasting.”
FCC Warnings
All transmitter adjustments other than those supplied by the manufacturer as front panel operating controls, must be made by, or under the supervision of, the holder of an FCC-issued general Radio-Telephone Operator’s License.
Replacement or substitution of transistors, regular diodes or other parts of a unique nature, with parts other than those recommended by Cobra, may cause violation of the technical regulations of Part 95 of the FCC Rules, or violation of Type
Acceptance requirements of Part 2 of the Rules.
